← TechnologyWhich outcome occurs when atmospheric ducting affects signal propagation using VHF marine band antennas?
A)Extended communication range results✓
B)Signal fading becomes extremely rapid
C)Reduced antenna radiation resistance
D)Polarization shift causes signal loss
💡 Explanation
Extended range communications occur because atmospheric ducting facilitates VHF propagation acting as a waveguide, therefore signals bend beyond the horizon, rather than attenuate normally. Signal fading is caused by multipath interference, polarization shift reduces received power due to misalignment.
